PIL.UnidentifiedImageError

[camipozas]

Describe the bug Different behavior on my computer to AWS EC2 instance m5.xlarge.

Expected behavior That they have the same behavior since it works on my computer, however when I execute it it cannot find the images.

Additional context

Function error

def read_pdf(pdf):
    """
    It takes a pdf file, converts it to images, and then converts those images to text
    :param pdf: The path to the PDF file you want to convert
    :return: A string with the text of the pdf
    """
    full_text = ''
    with tempfile.TemporaryDirectory() as path:
        images_from_path = convert_from_path(pdf_path=pdf,
                                             dpi=350,
                                             output_folder=path)

        for page in tqdm(images_from_path):
            full_text += image_to_text(page, lang='spa')
    return full_text

I printed the filenames to see if it was a path issue but it displays correctly. Additionally I am using multiprocessing, again in local it works but in the instance it does not.

Is this only happening with a single PDF? If you run pdftoppm -r 200 -jpeg your_file.pdf out does it show any warnings?
